Sound intensity decreases when what decreases?
Sound intensity decreases when the distance from the sound source increases. Sound intensity also decreases as the medium through which the sound is traveling becomes more dense or absorbs more of the sound energy.
Is it true that sound intensity decreases when the amplitude decreases?
Yes, the sound intensity is directly proportional to the square of the amplitude of the sound wave. Therefore, when the amplitude decreases, the sound intensity also decreases.
What rises and falls in sound intensity?
The amplitude of a sound wave rises and falls to create variations in sound intensity. As the sound intensity increases, the amplitude of the sound wave increases, resulting in a louder sound. Conversely, as the sound intensity decreases, the amplitude of the sound wave decreases, resulting in a quieter sound.
Does sound Intensity decrease linearly with distance?
No, it follows the inverse square law. That is, the intensity is inversely proportional to the square of the distance. I2/I1 = (r1/r2)². Intensity decreases with 1/r² from increased distance, while the sound pressure decreases only with 1/r from increased distance.
What is the relationship between sound intensity and distance?
The relationship between sound intensity and distance is that sound intensity decreases as distance from the sound source increases. This is because sound waves spread out as they travel, causing the intensity of the sound to decrease with distance.

When the intensity of a sound decreases what decreases?
That means that it gets weaker.In physics, intensity is defined as power per unit area.

The relationship between sound intensity and distance is that sound intensity decreases as distance from the sound source increases. This is because sound waves spread out as they travel, causing the intensity of the sound to decrease with distance.
If sound waves travel away from there source there what decreases?
As sound waves travel away from their source, the intensity (loudness) of the sound decreases due to the spreading out of the energy over a larger area. This phenomenon is known as the inverse square law, where the intensity decreases proportionally to the square of the distance from the source.
Decreasing of Sound Intensity?
Sound intensity decreases as the distance from the source increases due to the spreading of energy over a larger area. This decrease follows the inverse square law, meaning the intensity decreases proportionally to the square of the distance. Factors like obstacles and absorption can also contribute to the attenuation of sound intensity.
Which wave property decreases as you get farther away from the source of a sound?
The intensity of sound decreases as you get farther away from the source. This is because sound waves spread out in all directions, causing energy to be distributed over a larger area.
What happens to the volume of a sound wave as its amplitude decrease?
As the amplitude of a sound wave decreases, the volume or loudness of the sound also decreases. This is because amplitude is directly related to the intensity of the sound wave, which in turn affects how loud the sound is perceived. So, a lower amplitude results in a quieter sound.
What happens when the intensity of a sound decreases?
That means that it gets weaker.In physics, intensity is defined as power per unit area.
A surface receiving sound is moved from its original position to a position three times farther away from the source of the sound. The intensity of the received sound thus becomes?
Nine times weaker. Sound intensity decreases by the square of the distance from the source, so moving the surface three times farther away decreases the intensity by (3)^2 = 9 times.
